Part And Whole

This worksheet gives students direct practice with one of the most important percentage relationships: figuring out what percent one number is of another. Each problem provides a part and a whole, and students use the relationship Percent = (Part ÷ Whole) × 100 to find the missing percentage. With examples such as 5 out of 20, 18 out of 24, and 56 out of 80, students practice division, fractions, decimals, multiplication by 100, and percent notation while learning what “percent of a whole” actually means. It is especially useful for grades 5-6 students who are beginning percent problems and need a clear, repeatable structure before moving into word problems.

Learning Goals

• Identify the Part and Whole: Students learn which number represents the amount being considered and which number represents the total.
• Find the Fraction of the Whole: Learners divide the part by the whole to determine what portion of the total is represented.
• Convert to a Percent: Students multiply the decimal result by 100 and attach the percent symbol.
• Build Familiar Percent Relationships: Repeated examples help students recognize common results such as 25%, 50%, 60%, 70%, and 75%.

Classroom & Home Use

• Simple for Parents to Explain: A helpful question is, “How much of the total do we have?” Then divide that part by the total and turn the answer into a percent.
• Keeps the Skill Focused: There are no long stories to decode, so students can concentrate on the percent calculation itself.
• Supports Calculator or Mental-Math Practice: Depending on the student’s level, problems can be solved mentally, with written division, or with a calculator.
• Builds a Strong Foundation: The worksheet prepares students for percent-of-a-number problems, discounts, test scores, probability, and data.
• Easy to Use Anywhere: It works well for homework, centers, intervention, independent practice, or homeschool lessons.

The big idea in this worksheet is that a percent tells us how large the part is compared with the whole. Division, fractions, decimals, percent notation, multiplication by 100, and number sense all work together as students solve each problem. For parents, a simple example is 5 out of 20: 5 ÷ 20 = 0.25, and 0.25 becomes 25%. That is all the percent is doing-telling us that the part represents 25 out of every 100 equal parts. In classroom and homeschool settings, this worksheet gives students a dependable routine they can use again and again as percentage problems become more complex.
